As an investor of 48 years, having two engineering degrees and a 36year career as an analyst, I would say that the first hour or two ofDD gives you 90% of DD value.

What really counts is money management and discipline. I never short,never overpay, will buy more if it drops, but only to a predetermined limit.

The market offers many false lessons, but also a few real ones.For me, I never chase a fad, like green energy, a few years back.Also, I never made money on a biotech without a product, and always made money on a biotech with one. (There must bea lesson there somewhere.)
